Synthesis and Characterization for Pd(Ⅱ)—Sulfide and Sulfur Ylide Complexes

氯化-3,3-二氟-2-丙烯基二甲基锍及溴化乙氧甲酰甲基二甲基锍分别与钯的卤化物反应,生成双(3,3-二氯-2-丙烯基二甲基锍)四氯钯(Ⅱ)和双(乙氧甲酰甲基二甲基锍)六溴二钯(Ⅱ)。进一步反应转变为配合物。二氯双(3,3-二氟-2-丙烯基甲基硫醚)合钯(Ⅱ)和二溴双(二甲基乙氧甲酰甲基■叶立德)合钯(Ⅱ)。开通过元素分析、红外光谱、核磁共振谱等测试结果确定了它们的结构。

The salts of the complex anion-bis (3, 3 -dichloro-2-propenyldimethylsulfonium) tetrachloropalladate (Ⅱ) and bis (carbethoxymethyldimethylsulfonium) hexabromo-dipalladate (Ⅱ) are synthesized by the reactions of 3, 3-dichloro-2-propenyldimethyl sulfonium chloride and carbethoxymethyldimethylsulfonium bromide with the halides of palladate. Then, the reactions are proceeded and the complexes: dichloro bis (3, 3-dichloro-2-propenyl-methylsulfide) palladate (Ⅱ)and dibromo bis (dimethylsulfonium carbethoxymethylide) palladate (Ⅱ) are obtained. The structures of the complexes have been characterized on the basis elemental analysis, IR and 'H-NMR data. The four complexes are all new compounds.
